2. Locating Fireplace & Chimney
Location of the fireplace and chimney will affect performance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fire.
• Installing the fireplace in a basement is not recommended.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the fireplace location relative to floor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Section 5.
Recommended Location:
• Above peak
• Install the outside air kit with the intake facing prevailing
winds during the heating season.
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fireplace.
• Avoid installing the fireplace near doors, walkways or
small isolated spaces.
• Recessed lighting should be a “sealed can” design.
• Attic hatches weather stripped or sealed.
• Attic mounted duct work and air handler joints and seams
taped or sealed.
Recommended Location:
• Above peak
• Inside heated space
Marginal Location:
• Below peak
Marginal Location:
• Wind loading possible
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
Recommended:
• Insulated exterior chase

C.Construct the Chase
Round Termination Cap
A chase is a vertical boxlike structure built to enclose the
fireplace and/or its vent system. Vertical chimneys that
run on the outside of a building must be installed inside a
chase.
Storm Collar
Metal Chase Top
Ceiling
Firestop
In cold climates, Hearth & Home Technologies recommends that the chase be well insulated using batt type
insulation between the joists.
Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST
be checked.
False Ceiling
Chases should be constructed in the manner of all outside
walls of the home to prevent cold air drafting problems.
The chase should not break the outside building envelope
in any manner. All outer walls need to be insulated.
Tabs
Ceiling
Firestop
Insulation
Building codes require false ceiling and ceiling firestops/
attic shields at each floor of the chase or every 10 ft (3048
mm) of clear space to control spread of fire.
Walls, ceiling, base plate and cantilever floor at the first
level of the chase should be insulated (see Figure 3.3.)
Vapor and air infiltration barriers should be installed in the
chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that
the inside surfaces be drywalled and taped (or the use of
an equivalent method) for maximum air tightness.
Holes and other openings should be caulked with high
temperature caulk or stuffed with unfaced fiber glass
insulation.
Warning! You must install false ceilings and ceiling firestops at each floor of the chase or every 10 ft
(3.05 m) to control spread of fire.
Warning! Risk of Fire! Do not seal area between fire
stop opening and chimney pipe except where they enter
the attic or leave the warm air envelope of the home (use
600° F sealant).
• The chase is constructed using framing materials much
the same as the walls in your home. A variety of siding
materials may be used including brick, stone, veneer
brick, or standard siding materials.
• In constructing the chase, several factors must be
considered:
- Maintain a 2 in. (51 mm) air space around the
chimney.
- The chase top must be constructed of noncombustible material.
- In cold climates, a firestop spacer and attic insulation
shield should be installed in an insulated false ceiling
at the 8 ft. (2438 mm) level above the fireplace
assembly. This reduces heat loss through the chase.
- In cold climates, the walls of the chase should be
insulated to the level of the false ceiling as shown in
Figure 3.3. This will help reduce heat loss from the
home around the fireplace.

materials surrounding the chimney system.
• Insulation and other materials must be firmly secured to
prevent accidental contact with chimney system.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to prevent contact between insulation or other
materials and chimney system may cause overheating
and fire.

D.Frame the Fireplace
Notice: Hearth extension design must be determined
before installation of fireplace.
WARNING! Risk of Fire! Comply with all minimum clearances specified.
If the fireplace is placed on the floor, the maximum height
of a finished raised hearth is 3-3/4”, if you want a higher
raised hearth the fireplace must be placed on a platform.
• A minimum 1-1/2 in. (38 mm) air clearance must be
maintained at the back and sides of the fireplace
assembly.
• Chimney sections at any level require a 2 in. (51 mm)
minimum air space clearance between the framing and
chimney section.
Figure 3.5 shows a typical framing (using 2 x 4 lumber) of
the fireplace, assuming combustible materials are used.
All required clearances to combustibles around the fireplace must be adhered to. See Figure 3.2. Any framing
across the top of the fireplace must be above the level of
the top standoffs. (No recess above standoffs.)
The finished cavity depth must be no less than 28-1/2 in.
(673 mm) from the finished backwall to the outside of front
wall framing. Framing must extend straight up all the way
to the ceiling.
Warning! Risk of Fire! You must comply with all
minimum air space clearances to combustibles. Do NOT
pack required air spaces with insulation or other materials.
Caution! Risk of Cuts/Abrasions. Wear protective gloves
and safety glasses during installation. Sheet metal edges

G.Outside Air Kit
Outside air kits must be used for combustion and to provide cooling air to prevent overheating. Hearth & Home
Technologies recommends you utilize the shortest duct
run to optimize the performance of the outside air kit. The
outside air inlet hoods should be positioned in a manner
that will not allow snow, leaves, etc. to block the inlet. In
some installations the air duct may need to be run vertically. In such an installation, a 3 ft (914 mm) height difference must be maintained from the top of the uppermost

B.Offsets/Returns
• Use an offset/return to bypass overhead obstructions.
• An offset and return can be used as a single entity or separated by chimney section(s).
Warning! Risk of Fire! Do not use offset/returns greater than 30°. Chimney draft will be restricted and could cause
overheating and fire. Secure offsets with screws ( not to exceed 1/2” / 13 mm in length) Secure returns with strapping.
Straight chimney sections may be secured with screws. Keep chimney sections from separating or twisting.
• Measure the shift needed to avoid the overhead obstruction. Refer to dimension A in Figure 4.2.
• Find the appropriate A dimension listed in Table 4.3. The B dimension coinciding with the A dimension measurement in
Table 4.3 represents the required vertical clearance needed to complete the offset/return.
• Read across the chart to find the number of chimney sections/model numbers needed between the offset and return.
Example:
A
Your “A” dimension from Figure 4.2 is 14-1/2 in. (368
mm). Using Table 4.3 the dimension closest to, but not
less than 14-1/2 in. (368 mm) is 15-3/4 in. (400 mm) using a 30° offset/return.
B
Figure 4.2 Chimney Offset/Return
You determine from the table that you need 36-5/8 in.
(930 mm) (Dimension “B”) between the offset and return.
The chimney components that best fits your application
are two SL1112’s.

B.Assemble Chimney Sections
Use only those components described in this manual.
Substitute or damaged chimney components could impair
safe operation and cause overheating and fire.
C.Install Chimney Air Kit
• Required in Canada.
• Follow instructions included with accessory.
Attach either a straight chimney section or an offset to
the top of the fireplace (depending on your installation
requirement). Chimney sections are locked together by
pushing downward until the top section meets the stop
bead on the lower section.
The inner flue is placed to the inside of the flue section
below it. The outer casing is placed outside the outer casing of the chimney section below it. See Figure 5.2.
Notice: Chimney sections cannot be disassembled once
locked together. Plan ahead!
• Lock chimney sections and/or offsets/returns together by
pushing downward until the top section meets the stop
bead on the lower section.
• Pull on the top section to make sure it is fully engaged
and will not separate.
• You may use #6 or #8 sheet metal screws no longer than
1/2 in. (13 mm) to fasten chimney sections together. Do
NOT penetrate inner flue.
Warning! Risk of Fire! You MUST use screws (provided) to fasten offset/returns to chimney sections to
keep the chimney parts from twisting. Failure to do so
could cause fire.
• Fasten offset/returns to chimney sections. Insert the
screws (provided) through the predrilled holes. Do NOT
penetrate inner flue.
• Secure chimney returns with hanger straps provided;
fasten to studs or joists.
• Vertical straight runs of chimney must be supported every
35 ft (10.7 m).
Figure 5.2 Assembling Chimney Sections
Warning! Risk of Fire! Do NOT install substitute or
damaged chimney components.
20
Heatilator • Birmingham 36-B Installation Manual • 4059-709 • Rev H • 10/09/13
D.Secure Offset/Return
When offsets and returns are joined to straight pipe sections, they must be locked into position with the screws
provided* (outer only), using the predrilled holes. To prevent gravity from pulling the chimney sections apart, the
returns and the chimney stabilizers have hanger straps for
securing these parts to joists or rafters. See Figure 5.3.
* Use # 6 or # 8 sheet metal screw, or larger, no longer
than 1/2 in. (13 mm).

E. Install Ceiling Firestops
Warning! Risk of Fire! Do NOT seal area between
firestop opening and chimney pipe except where they enter the attic or leave the warm air envelope of the home
(use 600° F sealant).
Caution! Risk of Fire! Ceiling firestops must be used
whenever the chimney penetrates a ceiling/floor.
• Chase construction requires ceiling firestops at each
floor or every 10 ft. (3.05 m) of clear space.
• The ceiling firestop slows spread of fire and reduces
cold air infiltration.
• Install a ceiling firestop whenever chimney penetrates
ceiling/floor.
• Mark and cut an opening in ceiling as shown in Figure 5.4.
• Frame the opening with the same size lumber used in
the ceiling joists.
• Nail the ceiling firestop to the bottom of the ceiling joists
when there is a room above.
• Use an attic insulation shield if the ceiling is insulated.
The ceiling firestop may then be attached above or below
the joists.

►F. Install Attic Insulation Shield
Warning! Risk of Fire! You MUST install an attic insulation shield when there is any possibility of insulation or
other combustible material coming into contact with the
chimney.
Insert three
screws
• Do NOT pack insulation between the chimney and the
attic insulation shield.
• Failure to keep insulation and other materials away from
chimney pipe could cause fire.
• Do NOT offset chimney inside insulation shield.
Tabs bent 90°
Installation of a ceiling firestop is required:
• Refer to Figures 5.5, 5.6, 5.7.
• Roll the shield (around the chimney if already installed).
The three holes on each side will match up (large holes
on top).
• Insert three screws into the matching holes to form a
tube.
• Bend the tabs on the bottom of the tube inward to 90° to
maintain chimney air space.
• Rest the insulation shield on the ceiling firestop below.
• Bend the tabs at the top of the shield inward to 90° to
maintain the 2 in. (51 mm) air space from the chimney.
Figure 5.5 Prepare Attic Insulation Shield
2 in. (51 mm)
air space
Warning! Risk of Fire! Use of cardboard or other
materials that can deflect under humidity or other environmental conditions is not recommended.
• The shield or barrier must be tall enough to extend
above the insulation and prevent blown-in insulation from
spilling into the cavity.
• Maintain specified air spaces around chimney.
• Check instructions and local codes for further details.
Double-check the Chimney Assembly
Continue assembling the chimney sections up through
the ceiling firestops as needed. While doing so, be
aware of the height and unsupported chimney length
limitations given under Section 5.
Check each section by pulling up slightly from the top
to ensure proper engagement before installing the succeeding sections. If they have been connected correctly, they will not disengage when tested.

Finishing
A.Finishing Material
Refer to Sections 1.B. and Sections 1.C. for combustible/
non-combustible materials. Refer to Figure 7.1 for noncombustible zone.
These surfaces
may be covered
with non-combustible
material.
Warning! Risk of Fire! You must maintain clearances.
• Do NOT cover metal fireplace front with combustible
materials.
• Install combustible materials only to specified clearances
on top front and side edges.
• Apply metal lath to the metal face or non-combustible
board with corrosion-resistant, self-drilling, self-tapping
screws capable of penetrating the metal surface of the
fireplace face in preparation for final finishing material.
• Complete framing and apply facing material (drywall)
over framing.
• A bead of 300-deg F minimum non-combustible sealant
must be used to close off any gaps at the top and sides
between the fireplace and facing to prevent cold air
leaks.
• Large gaps can be bridged with fiberglass rope gasket.
• Only non-combustible materials may be used to cover
the metal fireplace front.

applied between finishing materials and
molded brick edges, bottom and sides.
The seam between finishing materials and
firebox top must be sealed with noncombustible sealant.
Noncombustible finishing
materials MUST overlap
side faces by 1 1/4 in. (32 mm)
to cover the edges of the
